Bibliography in LaTeX

The simplest bibliography for a report is the thebibliography environment at the end of the document. Each entry gets a key in \bibitem, and you cite it in the text with \cite. For longer papers, BibTeX with a separate .bib file is more convenient.

\begin{thebibliography}{9}
  \bibitem{halliday} D. Halliday, R. Resnick, J. Walker,
    \emph{Fundamentals of Physics}, Wiley, Hoboken 2014.
\end{thebibliography}

The value of the gravitational acceleration is given in \cite{halliday}.

Common mistakes

• Citation numbers typed by hand: once you add an entry, all of them shift.
• "[?]" in the PDF: a missing second compilation or a typo in the \cite key.
